Disclosed is the structure of a touch window. The touch window includes a transparent window, a touch sensor module on one surface of the transparent window, and a transfer film layer between the transparent window and the touch sensor module. The transfer film layer is provided in the touch sensor module to remove the structure of a printed pattern, so that the conventional problems related to the flatness caused by a printing step are solved, thereby improving the adhesive efficiency and expanding the realization range of various colors.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A touch window comprising: a transparent window; a transfer film layer under the transparent window; a touch sensor module under the transparent window and including a view area and a dead area, wherein the touch sensor module comprises: a base substrate; and a first sensing electrode pattern, a second sensing electrode pattern, and a wiring part on one surface of the base substrate; a first adhesive layer between the transfer film layer and the transparent window; and a second adhesive layer between the transfer film layer and the touch sensor module, wherein the first sensing electrode pattern and the second sensing electrode pattern are disposed on the same plane, wherein the transfer film layer comprises: a base layer; and a printed layer disposed on the base layer, wherein the printed layer is a sheet, wherein each of the first adhesive layer and the second adhesive layer includes: a first area corresponding to the view area of the touch sensor module; and a second area corresponding to the dead area of the touch sensor module, wherein the transfer film layer is disposed between the transparent window and the touch sensor module, wherein the printed layer and the base layer are disposed in an area corresponding to the view area of the touch sensor module, and wherein a first stack structure in the view area comprises the same layers stacked in the same order as does a second stack structure in the dead area, each of the first stack structure and the second stack structure comprising the transparent window, the first adhesive layer, the printed layer, the base layer, and the second adhesive layer stacked in order.
2. The touch window of claim 1 , wherein the second adhesive layer, the transfer film layer, the first adhesive layer, and the transparent window are stacked sequentially.
3. The touch window of claim 1 , wherein the first adhesive layer includes an optically clear adhesive (OCA).
4. The touch window of claim 1 , wherein the second adhesive layer includes an optically clear adhesive (OCA).
